ELECTRICAL HEATING APPARATUS.

Specification of Letters Patent.

Patented Sept. 14, 1920.

Application fi1ed May 23, 1919. Serial No. 299,188.-

regulated electrical heating apparatus such as an electrically heated boiler from which a supply of steam can be obtained in a few minutes with or without projection of hot water at a constant or uniform temperature -of or about 100 C. The apparatus also provides a method of heating by radiation of heat from the exterior surfaces and an atomization of water or other liquid by pressure and suction in a definite degree and in a definite or variable quantity.

By means of a boiler in accordance with the present invention, the results above enumerated can be obtained separately or simultaneously. It is regulated automatically and only absorbs the amount of current necessary to effectthe work required.

Reference is made to the accompanying drawing which shows diagrammatically in vertical section a boiler in accordance with the present invention.

To start the device in operation the valve 8 is first,-for a time opened, and may then be closed.

The action of the boiler takes place as follows 1 Water at a certain pressure is delivered to the apparatus 1 (a suitable pressure being that corresponding to a column of water of a height equal to the height of the apparatus) by a tube 2 and the current is supplied by the terminals 3, 4. The level of the water is raised in the interior of the apparatus between the electrodes 5 and 6 and acts as an electrolyte. area of the electrodes is such that the layer of water traversed by the current is rapidly brought to the boiling point and the point.

The superficial in the interior so that the water descends until the pressure of the vapor is equal to that of the exterior water, thereby reducing or momentarily interrupting the action of the current.

The vapor being at a temperature of at least 100 C., the walls of the apparatus and the Water in the lower part thereof are quicky raised to a temperature of about 100" In the first case the apparatus forms a radiator and a reservoir for hot water. The power as a radiator is proportional to the exterior radiating surface which surface maybe considerably increased by providing the surface with fins or ribs mo"- able or unmovable and its power as a hot Water supply tank is evidently proportional to the volumetric capacity of the lower part.

As the cocks remain closed, the temperature of the vapor and the parts of the apparatus remain the same so that in proport1on as the calories of the vapor are radiated into the external atmosphere or become absorbed by the water, the vapor becomes saturated, the pressure diminishes and the level of the water rises between the two electrodes and the same action again takes place. Shortly thereafter equilibrium is established between the pressure of the vapor, the pressure of the water, the heat produced, the heat absorbed and the current consumed. 1

If the cock 7 be opened in order to draw a certain quantity of hot water, the latter becomes replaced immediately by the cold water admitted by the tube 2, and the action of the apparatus is not at all modified. All the forces tend to restore equilibrium and any slight depression caused by the withdrawal of the water is immediately compensated by a partial condensation of the vapor, by a rise in the level of the water and a greater quantity of current.

If the steam cock 8 be more or less opened, it is evident that the liberated vapor will be immediately replaced by the ascending column of water between the electrodes 5 and 6, evaporation will take place more quickly than the level of the water rises, the thermo-electric power of the current being in the present case proportional to the immersed surface of the electrodes. This power may be such that the maximum supply from the vapor cock corresponds at least to the quantity of water which can be vaporized by the maximum electric power. In the contrary case, the hot water escapes and not the vapor.

If the cock 9 alone be opened, tepid or cold water can only be drawn from the apparatus. The tube 10 extends to the bottom of the receptacle where the cold or tepid water introduced into the receptacle remains by reason of its greater density.

If the cocks 8 and 9 be simultaneously opened, the vapor therein escapes and creates a partial vacuum at the upper extremity of the tube 10 and the cold water at the bottom of the apparatus under the double action of the interior pressure and external pressure rises in the tube 10 and escapes by the opening 11 where the vapor jet is atomized. The apparatus then acts as a humidifier.

The tube 10 may thus be placed in communication through the cock 12 with an exterior receptacle containing any suitable liquid capable for example of purifying the air. This liquid will, be drawn in through the opening in the cock 12 at the same time as the water passes through the cock 9 in order to be atomized and mixed therewith;

By manipulating the cocks 9 and 12, separate atomization of the water and the liquid delivered from the exterior can be obtained.

It may be observed that the apparatus functions quite regularly. If the current be inadvertently cut off, the cocks remaining open, the water quickly rises in the apparatus and when it reaches the level of the terminals, the float 13 rises and closes the valve 14 and the admission of water is cut off. If on the contrary the apparatus becomes empty, it is evident that no current will flow since the water acts as the conductor between the electrodes.

15 indicates a hemispherical baffle plate intended to cause the projection of the vapor or atomized water in a horizontal direction or at any desired angle thereto.

16 and.17 are air inlets for the purpose of eifecting atomization or vaporization of drops of water. 7

If the apparatus be used principally for heating, the exterior walls may be provided with ribs or fins to increase the power.

In the latter case the ribs or fins may be provided as readily removable attachments to the apparatus.

The arrangement would be applied preferably where the apparatus is intended to serve a plurality of purposes. It would consist for example in surrounding as much as possible of the surface of the apparatus with a sheet corrugated in a vertical direction and suitably secured to the apparatus; the hot .water or vapor provided by the apparatus could also be used in an exterior radiator of any existing form without departing from the nature of the invention.

Whatever may be the use to' which the apparatus is put, it should be connected to the water supply by a tube of insulating material such as rubber, fabric, leather-cloth, ebonite, porcelain or other suitable-material. This tube of insulating material ought to be about .75 meters long and should be interiorly in the form of a helical tube as shown in the drawing.

.The apparatus should be mounted on a tition inthe boiler, below the electrodes, andhaving an opening, means to supply water to the boiler, a valved steam escape for the boiler, a valve to close the opening in the partition, and a float to operate said valve.

2. In apparatus of the class described, a boiler having a valved steam escape nozzle, a tube leading from a point below the Water level to a point within said nozzle, said tube having a valved intake and also a controlling valve, a pair of tubular electrodes in the boiler and spaced from the top and bottom thereof, one of said electrodes being within and spaced from the-other, a horizontal partition in the boiler below the electrodes and having an opening, means to supply water to the boiler, a valved steam escape for the boiler, a valve to close the opening in the partition, and a float to operate said valve.

In testimony whereof I aflix my signature in presence of two witnesses.
